Finishing Configuration of Access Server

Now that you’ve installed OpenVPN Access Server, this documentation outlines next steps.

Find the URLs for your web server

When you complete the installation process on the command line, you will find the URLs for your admin UI and client UI as well as the username and randomly generated password for the admin account.

(password can be changed on Admin UI)

Admin UI

The Admin UI is the web-based GUI for managing your OpenVPN Access Server. We also refer to it as the Admin Web UI. Typically, it is the address of your server with /admin/ appended, for example

When you sign in to the Admin Web UI, you can manage the configuration, certificate, users, and so on as an administrative user. The web-based GUI provides simplified management of complex VPN features rather than having to run Linux-based commands and scripts.

Client UI

The Client UI is the web-based GUI where users sign in and download clients or configuration files. Typically, it is the address of your server, as an example.

When a user signs in here with the credentials as set up in the Admin Web UI, they can download pre-configured Connect clients for Windows and macOS. There are also links to the Linux, Android, and iOS client programs. You can also find a configuration profile to import into an already installed client.

Note: The web services by default run on port TCP 943, so you can visit them at and as well. The OpenVPN TCP daemon that runs on TCP port 443 redirects incoming browser requests so that it is slightly easier for users to open the web interface by leaving the :943 part out.

First time logging into Admin Web UI

Administrative User

For the first use of the Admin Web UI, sign in with the openvpn user created during setup. The user’s password is randomly generated and displays in the output at the completion of setup.

On OpenVPN Access Server 2.9 and older, you must manually set the password for the openvpn user with this command: passwd openvpn

You can now open a browser and enter your Admin Web UI address.

Invalid Certificate

OpenVPN Access Server’s web interface comes with a self-signed certificate. This allows you to sign in to the Admin Web UI right away. Since it’s self-signed, it triggers an expected warning. We recommend adding your own SSL certificate in the Admin Web UI to resolve this.

By clicking through to continue to the site, you can continue to the web interface. At the login screen, you can enter the username and password for your ‘openvpn’ user.


Setting up a hostname

We recommend using a hostname for your web interfaces and client connections, rather than the IP address of your server. It’s easier for clients and users to sign in with a domain such as than to use an IP address.

Refer to Setting up your OpenVPN Access Server Hostname and follow the steps there.

Setting up authentication

Authentication with Local, RADIUS, LDAP, SAML, or PAM

Once signed in to the Admin Web UI, you can configure user authentication. OpenVPN Access Server supports local authentication where you configure users in the Admin Web UI. You can also use an external authentication system with PAM, RADIUS, LDAP, or SAML.

The default is local authentication where Access Server manages your credentials. Under User Management, you can add users and define their permissions at the user, group, and global level. You can also integrate with an external authentication system using PAM, RADIUS, LDAP, or SAML. For example, you can set up a connection to an LDAP connector to integrate with Windows Server Active Directory.

OpenVPN Access Server 2.10 and newer supports using multiple authentication systems simultaneously. Refer to OpenVPN Access Server’s User Authentication System for more information.
